[lug] Booting Multiple Linuxes

[Elyse Grasso]

I think we're confusing each other...

/dev/hda1 gets mounted as /boot when 7.2 boots, and /dev/hdc1 gets mounted as 
/boot when 7.1 boots. 7.1 doesn't know /dev/hda1 exists and 7.2 doesn't know 
that /dev/hdc1 exists: once they are booted there is no problem. The only 
problem is telling lilo where to find stuff.
